What is NPL?
• World-leading science and technology
laboratory
• Directly-owned by BIS
• 550+ staff
• Working with and for business, academia
and government
• Science with impact

Power Measurement at NPL
NPL measures power to accuracies
of 40 parts per million – comparable
to detecting the power of
flashlight against the background
of the full set of floodlights at
Wembley Stadium.
Readings of every electricity meter in
UK homes can ultimately be traced
back to national standards.
Accuracies are necessary to support
the long chain of measurements from
primary standard through to peoples
homes.

Planning for the impact of renewables and increased use of HVDC
Renewables’ impact on network – e.g. voltage rise, power quality?
Instrumentation for networks
How many sensors required to determine power flow across network?
Where should they be located?
Determination of carbon savings of smart interventions
How to calculate the net carbon savings in smart interventions and allow
inter-comparison with other options?
Challenges we address

Phasor Measurement Units (PMUs)
“PMU testing and calibration have
become a major hurdle to the further
development and implementation of
PMU applications in power systems.
Utilities need the guarantee of
reliability and accuracy of PMUs and
also the seamless interchangeability
among the PMUs from different
vendors.” EPRI

Determination of Carbon
Savings in SmartGrid Trials
Challenge: To calculate the net carbon savings in a smart interventions in
a standard and rigorous manner for comparisons with others, for
example LCNF trials.
§ Smart Grids – choosing the right
topologies /techniques/technologies…
§ How much carbon does a given
scheme save ?
§ To scale-up from trials requires
rigorous data to make the right
decisions

Dynamic Demand Challenge Prize
Create a new product, technology or service that utilises data to
significantly improve the ability of households or small businesses to
demonstrate measurable reduction in carbon emissions by shifting energy
demand to off peak times or towards excess renewable generation.
Expected outcomes:
• Demonstrable shift in peak usage to off peak times
• Responsiveness to dynamics of supply of renewable energy
• Measureable reduction in CO2 emissions
